Estimate of the hadronic vacuum polarization disconnected contribution to the anomalous magnetic moment of the muon from lattice QCD

The quark-line disconnected diagram is a potentially important ingredient in lattice QCD calculations of the hadronic vacuum polarization contribution to the anomalous magnetic moment of the muon. It is also a notoriously difficult one to evaluate. Here, for the first time, we give an estimate of this contribution based on lattice QCD results that have a statistically significant signal, albeit at one value of the lattice spacing and an unphysically heavy value of the u/d quark mass. We use HPQCD’s method of determining the anomalous magnetic moment by reconstructing the Adler function from time moments of the current-current correlator at zero spatial momentum. Our results lead to a total (including u, d and s quarks) quark-line disconnected contribution to aμ of −0.15% of the u/d hadronic vacuum polarization contribution with an uncertainty which is 1% of that contribution

Fundamentals of public-private partnerships in the transportation sector : international methodologies of highway public-private partnerships and a framework to increase the probability of success and allocate risk

Thesis (S.M. in Real Estate Development)--Massachusetts Institute of Technology, Program in Real Estate Development in Conjunction with the Center for Real Estate, 2013.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Cataloged from student-submitted PDF version of thesis.Includes bibliographical references (pages 50-53).In 2009 the American Society of Civil Engineers (ASCE) gave the US infrastructure sector a grade D, based on the current and future needs of the nation's infrastructure and estimates that by year 2020, the US surface transportation deficit will reach $846 billion. Furthermore, in 2013 the US Congressional Budget Office estimates that the main source of highway funding, the Highway Trust Fund, will have insufficient capital to meet its shortfalls by 2015. As defined by the ASCE, infrastructure is the physical framework upon which an economy operates. Without immediate improvement and alternative solutions to fund the crumbling roadway network, the US will continue to struggle to find its way to economic prosperity. This thesis aims to give an overview of how private participation can play an integral role in revamping the US highway network and will outline several of the most important aspects of structuring a successful highway public-private partnership (PPP). Throughout the thesis, PPP is referred to as a long-term contractual agreement between a private entity and a public sponsor to construct and maintain an infrastructure asset. PPP is a complex and potentially dangerous partnership as it can inadvertently put the public at risk; however, it has also proven to be a very successful tool in many countries around the world. By examining the US highway sector and the history of transportation PPP's, this thesis analyzes failed and successful cases, as well as study partnership frameworks implemented in other countries. With this, the thesis attempts to educate stakeholders and spread awareness of how to identify and effectively allocate risks associated with PPP's. If structured and executed appropriately, PPP's will help the stakeholders in highway privatizations reach each of their respective goals and can help rebuild a sustainable highway network throughout the US.by Ryan Butler and Eunil Lee.S.M.in Real Estate Developmen

A systematic study of real estate core funds : herd behavior and performance attribution analysis

Thesis (S.M. in Real Estate Development)--Massachusetts Institute of Technology, Dept. of Architecture, Center for Real Estate, 2005 [first author]; and, (S.M. in Real Estate Development)--Massachusetts Institute of Technology, Dept. of Urban Studies and Planning, Center for Real Estate, 2005 [second author].This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Includes bibliographical references (leaves 57-58).The returns and portfolio characteristics of core funds were tested for evidence of herd behavior and performance relative to the NCREIF Property Index (NPI), using a proprietary database that included data from 1985 to 2004. Tests performed include descriptive statistics, regression analysis, and attribution analysis. Results indicate that herd behavior tends to be somewhat correlated with the NPI return. Through our disaggregate (fund specific) analysis, we find that herd behavior, where managers base investment decisions on the collective actions of the market rather than their individual beliefs, may be present in the core fund industry. Regression analysis suggests that herding appears to be positively correlated with fund size and negatively correlated to leverage, fees, and persistence from the one-year lag of the deviation from the mean. Performance analysis results indicate that although fund leverage has increased significantly over time, the use of debt has produced little or no additional return to investors. We found that across funds, net returns to real estate fall short of the NPI, and that across time, there is a negative correlation between the performance of the index and fund performance relative to the index.(cont.) Attribution analysis revealed that property selection returns have produced the greatest amount of return deviation from the NPI over time, and that selection and strategy returns are negatively correlated. Regression analysis suggests there is persistence in fund performance in the short term, that a fund's fee is positively correlated with gross returns, although that does not necessarily translate into higher returns to the investor, and that larger funds are negatively correlated with performance.by Valerie Kwong and George Ryan Robison.S.M.in Real Estate Developmen

A survey of boat-based recreational fishing in inner Shark Bay 2016/17

Monitoring the temporal and spatial variability in recreational fishing provides necessary information for assessing resource sustainability, monitoring resource allocation and informing fisheries management. This is particularly important in inner Shark Bay because recreational fishing occurs in a World Heritage Area and Marine Park. The majority of boat-based recreational fishers in inner Shark Bay target Pink Snapper (Chrysophrys auratus) and three genetically distinct stocks of this species occur in the Denham Sound, Eastern Gulf and Freycinet Estuary Management Zones

State-wide survey of boat-based recreational fishing in Western Australia 2013/14

Based on the outcomes of an international workshop on recreational fishing survey methods in 2010, the Department of Fisheries developed an integrated survey involving several methods to provide a robust and cost-effective approach for obtaining annual estimates of recreational catch by boat-based fishers at both state-wide and bioregional levels

Integrated survey of boat-based recreational fishing in inner Shark Bay 2018/19

Inner Shark Bay is a popular recreational fishing destination. As recreational fishing occurs in a World Heritage Area and Marine Park, there is a need for ongoing reliable information on catches. Many boat-based recreational fishers in inner Shark Bay target Pink Snapper (Chrysophrys auratus)

Statewide survey of boat-based recreational fishing in Western Australia 2015/16

The statewide survey of boat-based recreational fishing includes three components: (i) off-site Phone Surveys (encompassing an initial Screening Survey, a longitudinal Phone-Diary Survey, and Post-Enumeration Surveys); (ii) on-site Boat Ramp Surveys; and (iii) a Remote Camera Survey
